  Rezumat:  The Content of Assimilatory Pigments in Plantlets Grown under Shielded Magnetic Field Conditions. In order to survey how magnetic fields affect the synthesis of the assimilatory pigments, as well as the protein content of the cells, the vegetal material was incubated under low magnetic field and also in normal geo-magnetic environment. Plantlets of bean (Phaseolus vulgaris) and sunflower (Helianthus annuus) were incubated in a magnetic shield box and in a control box for 24, 48 and 72 hours, respectively. The shielding level was about 10-6 of the terrestrial magnetic field. As compared to the control, the chlorophyll, carotenoid and protein biosynthesis was stimulated in bean plantlets and inhibited in sunflower ones. The results support the idea that the shielded magnetic environment induces different reactions depending on the time of exposure and on the plant species.
